In the past, we had many discussions about bit depth and we had the luck that knowledgable people Like Nika Aldrich and Bob Katz came here to explain what digital recording was all about. They tackled all of the myths that are floating around about bit depth. Steinberg had a hard time explaining that 32bit floating Point was as good, if not better- than the 48bit fixed Point that PT used back then.
Even today, there is much ignorance and a lot of people think that “resolution” in audio means the same thing as “resolution” in video. Just yesterday I had a long discussionwith video people who insisted that the audio department worked in 24bit, because they would not take any compromise in terms of audio quality.
Anyway, I just came across this article; hope it is of some help.
